Yamaha TG-33
Tone Generator (1990)

 

The Yamaha Sy-22 vectorial-synthesis module version with some minor technical enhancements.

The TG-33 is an Interesting machine lo-fidelity based on a mix of low-fidelity PCM and FM synthesis called DASS technology,

info MODULE Main panel features a 16 x 2 lines backlit display, 35 buttons, 3 knobs and a special joystick ball for vector function control.

Rear panel terminal connectors:
- Midi interface
- main signal out
- AUX out dry.

 

ac Power supply is an external PSU +)- 700 mA 10V DC.




edit TECH main CPU HD6475328CP-10 (part of h8/523) system manages a total of 32 voices polyphony generated by a custom chip GEW5 (TMC3493PH), relative DAC is a IC YM3032.

STRUCTURE the TG33 voice system is based on Yamaha custom DASS - Dual Architecture Synthesis System - which mixes two syntheses:
- AWM PCM samples (16 voices)
- FM frequency modulation (16 voices).





editTG 33 ALGORITHM
AWM + FM STRUCTURE basic patch combines the DASS tones in 2 modes:
- 1 PCM + 1 FM
- 2 PCM + 2 FM.

 

8 bits wavetable

(UPPER) PCM are always assigned to TONE A-C and FM to TONE B-D, then elements can be mixed or detune using the apposite vector joystick.

 



edit
AWM SYNTHESIS the 1 MB PCM ROM contains 128 waveforms coded at 8 bits.


awm2 1mb Wavetable is organized into 16 instrument categories:piano, percussion, guitar, transient, organ, synth, bass, basic waveform, brass, FX, string, sequence, wood, hits, vocal and drum.






edit
FM frequency modulation engine is a 2 OP class with 8 harmonic sinewave variations.
Fm edit from panel is limited to basic parameters like feedback, while advanced functions like algorithm, waveform, frequency and others can be changed only by Midi Sysex commands.

2op The Tg33 includes 256 FM presets organized into 16 categories: piano, reed, percussion, FX, organ, pluck, synth sustain, brass, bass, synth motion, wood, string, decay, OSC1 basic, OSC2 basid FM and OSC3 basic FM2.




edit
EXPANSION the TG33 cannot be expanded, there are just some sound libraries available (also compatible with SY22 and Sy35) - pics from ebay auctions:

ENVELOPE 1 indipendent EG per ELEMENT:
- FM: 4 segments ADSR + 4 times
- AWM: 4 segments ADSR + 4 times.

EG
TIP: In addition there are 7 preset EG for common instruments, a special delay function which sets a time before engaging the EG and 16 kind of keysacaling models (for amplitude rate scaling).




edit VECTOR
function crossfades s the overall envelope applying a special defined motion traced by the joystick ball, then movement can be recorded in real-time and played back (also by Midi control change).

edit
PERFORMANCE up to 16 parts with individual settings:
- Midi channel
- stereo panning
- volume mix
- detune pitch
- analog out
- modulation amout (to aftertouch or wheel).

tech


edit LFO each tone features a single delayed modulator (shapes: saw-up, saw-down, square, sample & hold and triangle).



LFo MODULATOR destinations are:
1a- LFO FM amplitude
1b- LFO AWM amplitude
2a- LFO FM pitch
2b- LFO AWM pitch.




edit EFFECTS DSP Digital Signal Processor based on IC YM3413 (same as Sy55) with 16 effects no possible edit organized roughly in 3 sections:
- reverb: hall, room, plate, club, metal and gated
- delay: long or ping pong
- digital distortion.
demo HEAR internal reverb



edit MIDI just a few basic MIDI CC# but Midi Exclusives are supported.
Tg33 souds are partially compatible to Sy-22 keyboard model since performance has a different structure.



edit
MEMORY:
- 64 ROM patches
- 64 RAM patches
- 16 RAM multis
RAM can be doubled using special MCD32 or tripled using bigger model MCD64.
